Laboratory11-Hydroxy delta-9 tetrahydrocannabinol [Mass/mass] in Hair
Definition
Hair analysis provides a longer surveillance window for drug use than other methods because hair retains drugs longer (weeks or months, compared with days detectable in blood or urine). Collecting hair specimens also is less invasive than urine or blood sampling. Drawbacks for hair analysis include expense, and environmental contamination of the specimen.
